fatal error C1083

[Friso1990]

Hello,

I want to use Visual Studio 2010 Professional for unit testing, but I get the following error:

VectorTest.cpp(3): fatal error C1083: Cannot open include file: 'FARAOVector3D.h': No such file or directory

However, I know for a fact that that header exists, since I wrote it.

Do you know what is causing the problem and how I can solve it?

Thank you in advance,
Friso
